Final answer:
In biology, populations can grow out of control when there are no limiting factors.
Step-by-step explanation:
In biology, populations can grow out of control when there are no limiting factors. Limiting factors refer to any biotic or abiotic factors that restrict the growth, abundance, or distribution of a population within an ecosystem.
For example, consider a population of rabbits in a forest with an abundant food supply and no predators. In this scenario, without any limiting factors such as diseases, competition for resources, or predation, the rabbit population may increase rapidly and eventually reach unsustainable levels.
However, it is important to note that in natural ecosystems, limiting factors are typically present, which help regulate population growth and maintain a balance within the ecosystem.
